Abstract (en)

In a photoelectric conversion device driven by a current mirror circuit, the current mirror circuit is constituted by four transistors, e.g., first and second PMOS transistors (1, 2) and first and second NMOS transistors (3, 4). A photodiode (5) which has a cathode connected to the drain of the second PMOS transistor (1) and receives reverse bias is arranged. Electrons generated in the photodiode can prevent potential rise of a node connected to the photodiode to normally operate the photoelectric conversion device even upon irradiation of light. <IMAGE>
